Amazon Leadership Principles 行为面试全攻略

Amazon 的行为面试不是"走过场"，而是与算法题同等重要的淘汰环节。16 条 LP 每条都可能被问到，准备 20+ 个 STAR 故事是基本功。

LP 考察机制

Amazon 的面试流程中，至少会有 1 轮专门的 LP 面试（通常 45-60 分钟），此外每轮技术面试官也都可能被要求在面试末尾问 1-2 个 LP 问题。

面试形式

• Behavioral Questions：“Tell me about a time…”
• Situational Questions：“What would you do if…”
• 面试官追问：STAR 的每个环节都可能被深挖（How exactly? What did you say? What was the data?）

STAR 回答法

16 条 Leadership Principles（2024 版）

2021 年 Amazon 将 LP 从 14 条扩展到 16 条，新增了 “Strive to be Earth’s Best Employer” 和 “Success and Scale Bring Broad Responsibility”。

Tier 1：最常被问的 8 条（必背）

1. Customer Obsession（客户至上）

Leaders start with the customer and work backwards. They work vigorously to earn and keep customer trust.

核心：一切从客户需求出发，而不是从竞争对手或技术酷炫出发。

高频问题：

• Tell me about a time you had a conflict between customer needs and business/technical constraints.
• Tell me about a time you went above and beyond for a customer.
• Describe a time you received negative customer feedback and how you handled it.

STAR 范例：

S：实习期间负责内部数据平台，用户是公司的数据分析师。
T：收到反馈说查询界面加载慢（P95 > 10s），严重影响分析效率。
A：

1. 我主动约谈了 5 位高频用户，记录他们最常用的 10 个查询模式；
2. 发现 80% 的慢查询都缺少合适的索引，我分析了查询执行计划；
3. 添加复合索引的同时引入 Redis 缓存热点结果；
4. 上线后持续监控 P95，一周内从 10s 降到 500ms；
5. 编写了一份《查询优化指南》文档，帮助团队避免类似问题。
   R：用户满意度调研中平台评分从 6.2 提升到 8.9，我的方案被推广到 3 个 sister teams。

2. Ownership（主人翁意识）

Leaders are owners. They think long term and don’t sacrifice long-term value for short-term results.

核心：主动承担超出职责范围的责任，关注长期价值而非短期 KPI。

高频问题：

• Tell me about a time you took on something significant outside your responsibility.
• Describe a time you had to make a decision that was unpopular but right for the long term.
• Tell me about a time you fixed a problem that wasn’t yours.

STAR 范例：

S：团队接手了一个祖传代码仓库，CI/CD pipeline 经常失败，但没人愿意修。
T：我当时的职责是后端开发，Pipeline 归属运维团队。
A：

1. 我花了一个周末分析了最近 50 次失败日志；
2. 发现 70% 的失败源于测试环境数据库未正确清理（测试间数据污染）；
3. 我实现了一个 pytest fixture，在每个测试前自动重置数据库状态；
4. 同时迁移了 Travis CI 到 GitHub Actions，利用矩阵测试加速；
5. 主动写了一份 runbook 交给运维团队。
   R：Pipeline 成功率从 65% 提升到 98%，部署频率从每周 1 次提升到每天 3 次。运维 manager 专门发来感谢信。

3. Invent and Simplify（创新与简化）

Leaders expect and require innovation and invention from their teams and always find ways to simplify.

核心：不满足于"够用"，持续寻找更简单、更优雅的解决方案。

高频问题：

• Tell me about a time you invented something new or simplified an existing process.
• Describe a complex problem you solved with a simple solution.
• Tell me about a time you challenged the status quo.

4. Are Right, A Lot（决策正确率高）

Leaders are right a lot. They have strong judgment and good instincts.

核心：不是每次都对，而是有系统性的决策框架，能从错误中学习。

高频问题：

• Tell me about a time you made a wrong decision. What did you learn?
• Describe a time you had to make a decision with incomplete information.
• Tell me about a time you changed your mind after getting new data.

5. Learn and Be Curious（持续学习）

Leaders are never done learning and always seek to improve themselves.

核心：主动学习新技术、新领域，保持好奇心。

高频问题：

• Tell me about a time you learned something new outside your role.
• Describe a time you taught yourself a new skill for a project.
• Tell me about a time you were wrong about a technical approach and learned from it.

6. Hire and Develop the Best（培养最佳人才）

Leaders raise the performance bar with every hire and promotion.

核心：关注团队成长，mentoring 和 code review 都算。

高频问题：

• Tell me about a time you mentored someone.
• Describe a time you gave difficult feedback to a teammate.
• Tell me about a time you helped someone improve their performance.

7. Insist on the Highest Standards（坚持最高标准）

Leaders have relentlessly high standards.

核心：不满足于"能跑就行"，对代码质量、测试覆盖、文档都有要求。

高频问题：

• Tell me about a time you refused to compromise on quality.
• Describe a time you pushed back on a deadline to ensure higher quality.
• Tell me about a time you found a bug that others missed.

8. Bias for Action（行动偏向）

Speed matters in business. Many decisions and actions are reversible and do not need extensive study.

核心：在信息不完全时也要敢于决策和行动，不陷入分析瘫痪。

高频问题：

• Tell me about a time you made an important decision quickly.
• Describe a time you took a calculated risk.
• Tell me about a time you acted without manager approval.

Tier 2：中等频率（准备 2-3 个故事可覆盖）

9. Think Big（大局观）

Thinking small is a self-fulfilling prophecy. Leaders create and communicate a bold direction.

高频问题：Tell me about a time you proposed an ambitious project.

10. Frugality（节俭）

Accomplish more with less. Constraints breed resourcefulness, self-sufficiency and invention.

高频问题：Tell me about a time you delivered a project under budget or with limited resources.

11. Earn Trust（赢得信任）

Leaders listen attentively, speak candidly, and treat others respectfully.

高频问题：Tell me about a time you had to regain someone’s trust.

12. Dive Deep（深入细节）

Leaders operate at all levels, stay connected to the details, audit frequently, and are skeptical when metrics differ from reality.

高频问题：Tell me about a time you uncovered a problem by digging into the data.

13. Have Backbone; Disagree and Commit（敢于谏言，服从大局）

Leaders are obligated to respectfully challenge decisions when they disagree, even when doing so is uncomfortable.

高频问题：Tell me about a time you strongly disagreed with your team’s decision.

14. Deliver Results（交付结果）

Leaders focus on the key inputs for their business and deliver them with the right quality and in a timely fashion.

高频问题：Tell me about a time you delivered a project under tight deadline.

Tier 3：较新、频率较低

15. Strive to be Earth’s Best Employer（成为全球最佳雇主）

高频问题：Tell me about a time you improved team morale or culture.

16. Success and Scale Bring Broad Responsibility（成功和规模带来广泛责任）

高频问题：Tell me about a time you considered the broader impact of your decision.

故事准备清单

建议准备 20-25 个 STAR 故事，每个故事可以覆盖多条 LP。

常见错误

1. 用"我们"而不是"我"：面试官要找的是"你"做了什么，不是团队做了什么。
2. 结果不量化：“更快了"不够，要说"从 10s 降到 500ms”。
3. 只有成功故事：Amazon 非常看重"从失败中学习"，一定要准备 2-3 个失败经历。
4. 脱离 STAR 框架：没有清晰区分 Situation/Task/Action/Result 的回答会让面试官抓不住重点。
5. 选错故事：选择能体现"Amazon 级别"复杂度的故事，不要选课程作业级别的例子。
